Meaning & origin
Mackenna first appeared in U.S. records in 1986, riding the popularity wave of surname-inspired girls' names like McKenzie and Kendall. It reached its highest rank, 3211, in 2010 before beginning a gradual decline; by 2025 it had fallen to rank 3211 and was given to roughly 1 in 32,801 newborn girls. The name has been most popular in New York and Florida, reflecting its appeal in diverse urban areas. Mackenna remains a distinctly modern American choice, a creative respelling of the Irish surname MacKenna.
Mackenna is a modern feminine given name that likely originated as a respelling or variant of the surname MacKenna, which itself is an anglicized form of the Irish surname Mac Cionnaith (son of Cionnaith). The name has been used in the United States since the late 20th century, fitting a pattern of creating distinctive feminine names from surnames, often with the '-enna' ending.
